Recognizing early risk markers in young children with autism spectrum disorder (ASD) is critical for timely diagnosis and intervention. The purpose of this study was to extend previous findings regarding language milestones to a longitudinal design, in which ages of expressive language milestones (i.e., first words, first phrases) could serve as…

This article reports results from a longitudinal study from age 4 to 7 of comprehension and production of narrative macrostructure in Swedish monolingual children (N = 17). "Baby Birds/Baby Goats" from the Multilingual Assessment Instrument for Narratives (LITMUS-MAIN) were used to elicit narratives and ask comprehension questions at age…

Background: Children with language impairment (LI) show heterogeneity in development. We tracked children from pre-school to middle childhood to characterize three developmental trajectories: resolving, persisting and emerging LI. Methods: We analyzed data from children identified as having preschool LI, or being at family risk of dyslexia,…

Most international adoptees (IA) have rapid catch-up of the delays common at arrival. However, it is not known whether development at arrival predicts later abilities or school readiness. Therefore, we comprehensively evaluated language, fine motor, visual reception (VR), executive function (EF), attention (ATT), and sensory skills (SS) in IA…

The study found that mean length of utterance (MLU) and age were significantly correlated in both language impaired (N=24) and normal preschool children with rates of MLU change also similar for both groups of children. (DB)

Cross-cultural differences in emotional expressions following disappointment were examined in 59 Chinese American (CA) and 58 European American (EA) children. Children aged four or seven participated in a disappointing gift situation. Dimensions of expressive behaviors following disappointment were coded and included positive, negative, social…

This study examined qualitative developments in 96 school-aged children's expressible knowledge of 434 words (selected to represent dictionary contents). Developmental changes were found in proportions of high quality definitions, semantic and syntactic form, effects of parts of speech, morphological composition, and lexical organization. Results…

The study evaluated whether specifically language impaired (SLI) children (N=6 and ages 5-8) manifested atypical or normal but delayed development in their interpretation of PRO (an empty pronomial element which has also been termed "a missing complement subject"). Language samples were taken and analyzed twice over a 9-12 month period. Among…

A study examined theory of mind acquisition in 34 children (ages 5- 10) with deafness using four traditional false-belief tasks. Results indicate the age of the child was strongly related to theory of mind development and that the children were delayed by approximately 3 years in this cognitive developmental milestone. (Contains references.)…

A study examined the long- and short-term spectral characteristics of speech simultaneously recorded at the ear and at a reference microphone position. Twenty adults and 26 children (ages 2-4) produced 9 short sentences. Children's vocal levels were low in amplitude at both the ear and at the microphone position. (Contains references.) (CR)

Examination of the profiles and developmental trajectories of adaptive behavior of 80 children with Down's syndrome indicated a significant weakness in communication skills (especially expressive language), relative to daily living and socialization skills. Children ages 1-6 showed significant age-related gains in adaptive functioning, but older…

Twenty-eight toddlers with slow expressive language development were compared to normally speaking age-mates and found to show delayed rather than deviant development in the average level of complexity of their syllable structures, the number of different consonant phonemes produced, and the percentage of consonants correctly produced in…

Longitudinal change in syntax comprehension and production skill, measured over six years, was modeled in 31 individuals (ages 5-20) with Down syndrome. The best fitting Hierarchical Linear Modeling model of comprehension uses age and visual and auditory short-term memory as predictors of initial status, and age for growth trajectory. (Contains…

This study examined developmental changes in lexical comprehension in 100 bilingual individuals at five age levels, all of whom had learned Spanish as a first language and English beginning at age 5. Although skills improved in both languages over time, by middle childhood performance was better in English, with this transition occurring earlier…

The profiles and developmental trajectories of adaptive behavior were cross-sectionally examined in 80 children with Down syndrome ages 1 to 11.5 years using the Vineland Adaptive Behavior Scales. Profile findings indicated a significant weakness in communication relative to daily living and socialization skills. Within communication itself,…
